Discharging a Capacitor Definition: Discharging a capacitor is defined as releasing the stored electrical charge within the capacitor. Circuit Setup: A charged capacitor is connected in series with a resistor, and the circuit is short-circuited by a switch to start discharging.
Discharging a capacitor means releasing the stored electrical charge. Let’s look at an example of how a capacitor discharges. We connect a charged capacitor with a capacitance of C farads in series with a resistor of resistance R ohms. We then short-circuit this series combination by closing the switch.
Charge and discharge voltage and current graphs for capacitors. Capacitor charge and discharge graphs are exponential curves. in the above circuit it would be able to store more charge. As a result, it would take longer to charge up to the supply voltage during charging and longer to lose all its charge when discharging.
When the switch is closed, current flows in the circuit until electrons from the negative plate neutralize the positive charges on the positive plate. Figure 37.1.1. A simple capacitor discharging circuit. Rate of discharge depends on the current value of charges on the plates, which leads to charge decaying exponentially.
Circuit Setup: A charged capacitor is connected in series with a resistor, and the circuit is short-circuited by a switch to start discharging. Initial Current: At the moment the switch is closed, the initial current is given by the capacitor voltage divided by the resistance.
When a voltage is placed across the capacitor the potential cannot rise to the applied value instantaneously. As the charge on the terminals builds up to its final value it tends to repel the addition of further charge. (b) the resistance of the circuit through which it is being charged or is discharging.
